Results of dc magnetization study are presented showing interesting thermomagnetic history effects across the antiferromagnetic to ferromagnetic transition in Ce(Fe$_{0.96}$Al$_{0.04})_2$. Specifically, we observe (i)ZFC/FC irreversibility rising with increasing field; (ii) virgin curve lying outside the envelope M-H curve. We argue that these effects are quite different from the characteristics seen in spin-glasses or in hard ferromagnets; they can be understood as metastabilities associated…

Metastability in the ferrimagnetic–antiferromagnetic phase transition in Co substituted Mn2Sb
A detailed investigation of the first-order ferrimagnetic (FRI) to antiferromagnetic (AFM) transition in Mn1.85Co0.15Sb is carried out. These measurements demonstrate anomalous thermomagnetic
Metastable magnetic response across the antiferromagnetic to ferromagnetic transition in Gd 5 Ge 4
Results of isothermal magnetization and magnetic relaxation measurements are presented probing the nature of the magnetic-field-induced magnetostructural transition in the intermetallic compound
Kinetic arrest related to a first-order ferrimagnetic to antiferromagnetic transition in the Heusler compound Mn2PtGa
We report a magnetization study of the Heusler compound Mn2PtGa that shows the existence of a magnetic-glass state. Mn2PtGa shows a first-order ferromagnetic (FM)/ferrimagnetic (FI) to
Sharp magnetization step across the ferromagnetic-to-antiferromagnetic transition in dopedCeFe2alloys
Very sharp magnetization step is observed across the field-induced antiferromagnetic-to-ferromagnetic transition in various doped CeFe 2 alloys, when the measurement is performed below 5 K. In the
Concentration dependence in kinetic arrest of the first-order magnetic transition in Ta doped HfFe2
All three compositions studied show a reentrant transition in the zero-field-cooled warming curve and non-monotonic variation of the upper critical field and the region in H-T space where these features of kinetic arrest manifest themselves increases with increasing Ta concentration.
First order magnetic transition in doped CeFe2 alloys: phase coexistence and metastability.
Clear visual evidence of magnetic phase coexistence on micrometer scales and the evolution of this phase coexist as a function of temperature, magnetic field, and time across the first order FM-AFM transition is presented.
Giant negative magnetoresistance and kinetic arrest of first-order ferrimagnetic-antiferromagnetic transition in Ge doped Mn 2Sb
The effect of partial substitution of Ge for Sb on the first-order ferrimagnetic (FRI)–antiferromagnetic (AFM) transition in Mn 2Sb has been studied. It shows that the transition temperature (T t)
